SACHUSETTS, A CORPORATION 015 RHODE HANDLE CONSTRUCTION FOR BRACES ANDTHE LIKE.

Application filed April 18,1921. Serial No. 462,386.

struotions tor Braces and the like, of which the following is aspecification.

This invention relates to the construc- 10 tion or handles and moreparticularly, handles "for braces andthe like. One of the objectsthereof is to provide a device of the aijiove nature, simple andpractical in con struction and etlicient in action. Other objects are toprovide a construction the above nature which can be readily and cheaplymanufactured, which will be light and durable and which will becharacterized by an economical use of metal and avoidance 20 ofweakening of the (To-acting parts. Qther objects will be in part obviousand in part pointed out hereinafter.

The invention accordingly consists in the features oi construction,combinations of elements and arrangement of parts which will beexemplified in the structure hereinafter described and the scope of theapplication or" which will be indicated in the following claims.

In the accompanying drawings in which is shown one of various possibleembodiments of this invention,

Figure 1 is a sectional elevation thereof;

Figure 2 is a cross section taken substan tially on the line 2 2 ofFigure 1;

Figure 3 is an end view of a handle device;

Figure is an end view of one of the component members thereof; and

Figure 5 is a sectional view along the line of Figure 3.

Rimilar reference characters refer to simi lar parts throughout theseveral views of the drawings.

Referring now to Figure l. of the drawings. there is shown at thecentral or crank portion oi: a brace, the crank members 11 and 1.)running respectively to the end thrust handle and to the device rotatedby the brace such as a socket wrench, neither ot'which is shown hereinas they form in themselves no part of the present invention.

Mounted upon the straight portion 13 of this member is handle devicewhich comprises a pair of identical steel stampings 1 1, an end view ofone 01 which is shown in Figure 4}. These steel stampings aresemi-circular in general contour and complement each other in forming ahandle of a general tubular construction. Each of the handle members isoutwardly rounded as at 15 throughout substantially its entirelength andat each end is flanged outwardly as shown at 16, the outwardinclinationof this iiangc with respect to the axis of the mom her being preferablyin the neighborhood of seven degrees.

At each endo't the handle member thus formed there is provided a collar17, best shown in Figures and 5 of the drawings. This collar hasa'central opening 18 adapted to it and yet turn itreely upon the memberEach of these members moreover is provided with an annular recess 19having in its original torin an inner ivall 2O tapered to ht the outwardinclination of the flange 16. The outer wall 21 of this recess isnormally cylindrical.

In assembling the parts the members 17 are inserted over one end of thebrace and moved down substantially into the position shown in Figure oithe drawings and having their annular grooves 19 facing each other. Inorder to prevent movement of these members toward each other, there areprovided a pair of sleeve pins 22 fixedin the member 13 andsubstantially engaging the inner edges of the collars as shown in Figure1 of the drawings.

The pair of members 14: are then assembled to form a tubular handle andtheir flanges 16 are inserted within the recesses 19 ot the adjacentcollars 17. With the parts in these positions the outer wall of therecesses 19 is forced inwardly in such manner that it grips tightly theouter surface of the flanges 16 of the handle. The pressure by whichthis is achieved is carried to such an extent that the parts aresubstantially inseparable. I

in this inaunerthe handle member is not only light and rigid butextremely strong, and turns freely upon the portion 13 of the crank ofthe brace. Furthermore without any substantial weakening of this crankmember the handle is held against longi tudinal movement by the pins Then11tward inclination of the flange '16 interlocks with the rigid wallsof the collar 17, thus precluding the chance ,of endwise separation ofthe collars; and it will be seen that so long as the collars are inposition a lat eral separation of the members 14 is prevented. is asimple smooth cylindrical bearingbetween this handle and themember 13,the friction in turning is reduced to a minimum. As various possibleembodiments might be made in the above invention and as various changesmight be made in the embodiinent above set forth, it is to be understoodthat all matter herein set forth or shown in the accompanying drawingsis to be in terpreted as illustrative and. not in a limit inn sense. v

I claim as my invention:

1. In handle construction for braces and toward the other, the Walls ofwhich enclose a recess shaped to conform to the shape of the adjacentend of said hollow member into which the adjacent end of said hollowmemher is fitted, the-sides of said recess being pressed into grippingengagement with said end. i 3. In handle construction for braces and thelike, in combination, a hollow member,

and a pair of collars each journaled upon thebrace and each havingamgroove facing toward the" other, the .walls of which enclose a recessshaped to conform to the shape of' theadjacent end of said hollow memberinto which the adjacent end of said hollow member is fittechthe sides ofsaid recess being pressed into gripping engagement with said end, saidhollow member being built up of a plurality of longitudinal sections.

4. In handle construction for braces'and' the like, in combination, ahollow member having its ends inclined outwardly with respect to itsaxis, and a pair of end members having similarly inclined annularrecesses formed therein in which said ends are fitted It will also beseen that as new and between the walls of which they are gripped.

5. In handle construction for braces and the like, in comblnation, ahollow member provided with grooves into which said tlared ends rest andwith which they interlock.

7; In handle construction for braces and the like, in combination, ahollow member having a convex body portion and outwardly flared ends,and a pair of end c01- lars provided with grooves into which said flaredendsrcst and with which they interlock, said hollow member being; builtup of a pluralityof longitudinal sections.

8.In handle construction for braces and the like, in combination, ahandle member having bearings at its ends upon the crank portion of thebrace, and a pair or parts secured to and outwardly projecting from thesurface of said crank, one adjacent each end of said handle member andada ited to engage the inner surface of said handle and preventlongitudinal movement thereof.

9. In handle construction for braces and the like, in combination, ahollow handle built up of a plurality of longitudinal sections formed ofsheet metal and 'eachprovided with an inclined ed e portion, a pair ofend collars having similarly inclined annular recesses formed thereinadapted to receive and grip said edge portions and support'saidhollowmember rotatably upon the crank portion of the brace, and a pair ofparts projecting from the surface of said crank portion adapted toengage the inner surfaces of said collars and limit the longitudinalmovement. oi the handle v 10. In handle COI'ISlJIUCtlOH for braces andthe like, in combination, a hollow handle member having outwardly flaredend portions, apair of collars one at each end of said hollow handlemember each having a portion journaled upon the brace and a portionspaced from said portion, said two spaced portions forming a recessinclined similarly to the flared ends of said handle member and in whichsaid ends are gripped. In testimony whereof, I have signed my name tothis specification this eighth day of April, 1921.
